To all whom it may concern Be it known that I, JOHN WILLIAM Coon, ofEastleigh, Didsbury, in the county of Lancaster, England, haveinventedcertain new and useful Improvements in Knotting ficatio p My inventionrelates to .a device for the Devices, of which the following. is a specipurpose of tying knots in yarns, threads.

twine or the like."

' My invention comprises a novel form of knotting device comparativelylight in weight and having the mechanisms for operating. the knottingbill and the drawingofi' device inclosed.

'My invention further comprises an arrangement of parts who by the knotcan be tightened and the said lin ofi device driven from the samegearing which drives the knotting bill and an arrangement ofparts-whereby the said pull Figure 1 of-the accompanying drawing is 'a.front elevation of my improved knotting device. to Fig. 1 with coverremoved. Fig. 3 is a plan view. Fig. 4 is a section view through.

12. Fig. 5 is a side elevation. W

In a preferred construction I employ asuitable metal casting or the likeA in'fthe' form of a case or box and having a down-- .wardly projectingextension B which fits against the hand of the operator. Within the caseA Im'ounta short transverse'sha ft C or the like carrying a smallprimary quadrant D the said quadrant 1) having teeth out in its face..The transverse shaftC extends through the cover A of the case and tothe projecting portion C a handle E having a thumb piece E is attached.

The teeth of the quadrant D "mesh with g-the' teeth of a small pinion -Fsuitably mounted and carryin a secondary quadrant I. or segmental rack,I prefer to employ aknown form of knotting bill I the said knotting billbeing carried upon a shortver- 0t pulled-ofi' the knotting bill by meansof a rotatable pulling Fig. 2 is a, front elevation similarSpecification of Letters I'atent.

tical shaft K suitably supported and rotatable upon a stud, or bearingpoint L. The knottlng bill I may either comprise a single plece suitablysplit or cut to form two outer jaws or members or two'separate jawmembers between which is disposed a movable jaw member. Formed as partof or attached to the case A is a collar or flange M which collar orflange surrounds the vertical shaft K carrying the knotting bill and iseccentrically disposed in relation to the axis of the said knotting billshaft. As is known I form the movable jaw member with a cam shaped shankwhich upon the rotation of the shaft K comes in contact with the innerface of the collar or flange M being consequently actuated by the flangeor collar. The knotting bill is sharpened in the usual manner to insurethe severance of the threads when desired.

Upon {the knotting bill shaft K a toothed wheel N is mounted whichengages with the teeth of the secondary quadrant or rack H.

It will be understood therefore that movement of the rack H in eitherdirection will impart movement to the wheel N and consequently to. theknottingbill shaft K. I employ a loop'tightener and drawing as hook Owhich is carried on or forms part of a second vertical'shaft or rod Pwhich is parallel with the shaft K. The said drawing off hook projectsthrough the upper portion of the case A iin close proximity to theknotting bill '1. Upon the shaft P, I mount a toothed wheel R havinghelical or other suitably sd'aped teeth the teeth of the said Wheel Rmeshin with the teeth of the quadrant or.

rack H. form with the case cover A or 1 attach to the'said cover or toany convenient part of the device a hook or the like S. I attach thecase cover A to the case A by means of screws T or other suitable means.The yarns or threads V are placed under the hook of the drawing ofldevice 0 beneath the knotter bill I and 'under the stationary hook S.'The thumb piece E is depressed andthe shortshaft C rotated bringingabout the rotation of the knotting bill shaft K. The knotting bill Iacts in the manner of known knotting bills to form the knot and severthe ends. The drawing ofi device 0 which rotates with the knottin'g billI serves to draw theknottight and to draw the knotted threads clearofthe knotting bill when the loose ends have been severed. The parts arereturned to their orginal positions by means of a spring X which isthreaded on and controls the short transverse shaft C.

- I can employ any form of spring arranged in any suitable manner tocontrol the transverse shaft C and the handle E and thumb piece E.

lVhat I claim as my invention and desire to secure by Letters Patent is:v 1. A knot tying device comprising a closed casing having substantiallyiiat sides and a curved wall connecting the sides, a loop tightener anda knotting bill rotatably F mounted in said case and having theiroperacasing having substantially flat sides and a curved wall.connecting the sides, a loop tightener and a knotting bill rotatablymounted in said case and having their operative portions projecting fromthe curved wall of the casing, the axes of rotation being parallel, andgearing within the casing, in-

cluding a primary and a secondary quadrantand r tary toothed membersmeshin with said quadrants, for effecting the relative operation of thetightener and bill.

3. A knot tying device comprising a closed casing having substantiallyflat sides and a curved wall connecting the sides, a handle extendingrigidly from the casing, a loop tightener and a knotting bill rotatablymounted in said casing and projecting through the wall opposite thehandle, the axes of rotation of the tightener and bill being parallel,and gearing Within the cas ing including a primary and a secondaryquadrant and rotary toothed members meshing with said quadrants, toeffect the rela tive rotation of the tightener and bill.

4. A knot tying device of the character described comprising a closedbox or case, a

knotting bill having a shaft mounted in said case, a loop tightener andknot drawing-off device having a shaft mounted in said case, a toothedquadrant or sector, a pinion, a secondary toothed quadrant or sector, atoothed wheel mounted on the knotting bill shaft and engaged with saidsecondary quadrant or sector, a helical gear secured to the shaft of theloop tightener and also meshing with said secondary quadrant or sector,and a spring controlled thumb piece and connec-.

tions therefrom for actuatingthe said quadrants.

In testimony whereof'l have afiixed my signature, in presence of twoWitnesses.
